Application filed March 21,1905. Serial No. 251,300.

To all whom it may concern:

lie it known that I, llmnr' W. E. inis, a. citizen of the United Stateand u resident ot Lincoln in the county oi Lancaster and Suite ofNebraska, have ii.i vented certain new and useful improvements in Writsingdt chines, of which the following is a specification.

M tion relates to writing machines and is more particularly aid-optedfor use in stencil liliih'lllg machines.

The main object of the invention is to produce an improved constructionof such machines.

To this and other ends the invention resides in the features ofconstruction, arrangements of parts and combinations or" devices to behereinafter lully forth and particularly pointed out in the claims.

In the accompanying drawings. Figure l is avertictil, jront-to-rearcentral sectional view of a machine enibodying one form of my invention.Fig. 2 is 11- frag fragmentary front view of the upper part of the mahine and showing the carriage raised to expose the stencil sheet or workelement. Fig. 4 is an enlarged detailed sectional view taken on the linerc-x of Fig. Figs. 5 and 6 are enlarged detail face iiiid sectionalviews respectively of one of the type heads.

In the drawings, the main [mine of the machine comprises a base 1,corner posts 2 and a top plate 3. Keylevcrs 4 are pivoted at 5 in therear of the base and each key lever is formed with hook-like portion (3and is provided with a restorin 'spring 6". Spncin D levers 7 are alsopivoted at 5. Each key lever is connected by a link 8 with av sub-l ver9 pivoted at 10 in series fixedly secured in any suitable manner to thetop plate 3. Pivoted to each hanger at 12 is it type bur 13 which isadapted to co-act with and be actuated. vby its associate sub-lever 9.The free end of each type bar is provided with :1 type T4, the operatinglace whereof is suitably formed for stencil cutting or puncturing. Ihave shown herein and most clearly in of needle points 15, the needlesor wires 16 being en1-, i bedded and held in a suitable composition 17which is retained in a cup-like depression in the type block by a cap18. It is to be understood, however, that any other construction of typesuitable for puncturing or cutting the work element may be employed. 7

The type bars are ndnpted to cooperate with a rectangiilar flat platen19 which is preferably formed of metal,- the top being cut away at 20for the sake of lightness. The under face of the platen is provided witha covering or their)" fit of felt or other suitable material. Fixedlyattached to the side faces of the platen are retaining pieces 22 whichcooperate with the bottom face of the platen to form guide ways orgri'iovcs for the stencil slice ir plzit e whi h is indicnted by thel'ffi tfl'tll'fl, (I. A retaining piece 2?, i suitably attached to thepl-ut ri and extends longitudinally thereof at the ba -l serving nsliesi indicated in Fig. l, to guid iiiid control the it'ill edge of thostencil or wt sheet. lug ll secured to ilic trout i'" platen id aboutet-nti'iilly thirst-oi is perioraied to receive a .ncil holding member.The holding incinbcr herein shown compri es u gripping linger 25 whichtor iinates ;it the bottoii'i in ii holding portion iti' and is providedat the top with -.i tingi'a' button .27. coiled spring 2.; surrouiidsthe grippin" linger .llltl is confined between the top of the b a inglog 24 nnd the linger button 2", said spring serving noriinilly to pressthe holding portion 26 against the stencil a. The platen l9 is iiitnblyi'nouiited iii a. platen or carriage 29, which, herein shown, coinpfront member or b 0i and n lt'itl lmr 32, the side bars being lixodlyconnected with the front :ind rear bars by itllgltf pieces l3 and screws5' The platen 19 may be mounted in the platen carrier 29 in anypreferred manner. tongue and groove mounting is shown in the drn rigs,the right and left hiind sides of the platen being provided withprojecting portions which lit into grooves iornied longitudinally oi theside burs 3i, thisorraiigoinent perniitl ing ol the lore and alt niovenient ol the platen in the platen (ii 101'. A yoke piece 37 is lixedlysecured to the rear bar 32 of the plzileii frame. A draw 51 ring 38,having ilsi01'\\':i.1(l end si cured to it pin 32 projecting upwardlyfrom the front part of the platen l9 and its rear end secured to u hool10 fixed to the yoke piece 37, tends constantly to pull the platen 19 tothe rear ol the platen :arrier.

The lront nieinber orbar 3t) ol' the plnten carrier is provided with a.pztir of rollers 18 which run in Mill are guided by a groove wziy orllili'jli =1!) suitably mounted on the l'rarne of the machine. The yokeplitfil 37 at Cri a universal bar (55.

the rear of the platen carrier is bifurcated, as best appears in Fig. 1,so as to partially embrace or surround cars 50 projecting inwardly fromthe side arms 51 of a carriage truck 52. The ears 50 and arms 51 arepcrio rated to enable the side arms 5i to be slid-ably mounted on a backrail 53 fixed on standards 54 rising from the top plate. The carriagetruck is provided with rollers 55 which cooperate with a groove. 56formed in the top of the back rail 53. The connection between the platencarrier 29 and the carriage truck 52 is such that the carriage may beswung upward about the carriage truck as indicated in Fig. 3, thebilurcated portions of the yoke ,piece 37 turning on the bearing ears50of the truck. The sides of the yoke piece 37, however, are confinedbetween the side arms of the carriage truck so that the latter and theplaten carrier move together from side to side of the machine.

A toothed cscapement rack 57 is fixed to the rear of the carriage truck.Adapted to cooperate with the es capement rack are carriage feed dogs 58which are suit ably mounted on anupright arm 59 of a pivoted springrestored dog carrier 60, the horizontally disposed arm, 6] of saidcarrier being connected by a link 62 With a universal bar frame 63 whichis pivoted at 64 in the rear of the machine base and carries at itsforward end As best seen in Fig. l, the universal bar stands beneath theseries of books 6 on the key levers 4 A spring drum 66, pivoted in afixed bearing pressed down and then turned so that the holding per-,

67, is connected by a strap 68 with the carriage truck and tendsconstantly to draw the latter, and with it the platen carrier, leftwardacross the top plate of the nut-- chine. A pointer 69 secured to thefront rail 49 cooperates with a scale 70 on the front of the platencarrier:

The operation of the machine will be readily understood. The springmounted gripping finger 25 is first tion' 26 is rotated out of the holdof the platen. The

Work element or stencil plate a, which is usuallfcom: posed ofCardboard, thin metal or the like,'is then inserted between the face ofthe platenand'the guide members 22 and pushed back until its bottom edgeenters the space between the face of the platen and the rear guidemember 23. The gripping finger or holding member 25 is then manipulateduntil the holding portion 26 is in the position indicated in Fig. 1,wherein it will be noted the gripping finger serves to press the top ofthe stencil sheet or plate aagainst the face of the platen. The stencilsheet being in place the ban; die 44 is lifted to' the dotted lineposition in Fig. 1, thereby releasing the line space member 43 from thecletent 46 and allowing the draw spring 38 to draw the :platen to therear of the platen frame as indicated in Figs. 1, 2 and 3. The linespace member is then lowcred, the parts being so-pr oportioned that theforemost perforation45 will engage with the detent 46. The

' platen carrier is then positioned for beginning the line by means ofthe pointer 69 and its cooperating scale 70.

I When a key lever i is adequately depressed the type bar'13 associatedtherewith is, throughthe connecting link 8'andsub-lever 9, swungupwardly causing the needle pointtype to follow a path such as isindicated bythe dotted line in Fig. l and to perforate the stencil sheeta; As the lever'is swung downwardiy its hook 6, acting on the'universalbar65, swings, the universalbar framedownwar dly about its pivot 64,theref of myinvention.

by, through the link 62, actuating the dog carrier 59 and causing thedog members 58 to cooperate in a known manner with the feed rack 57, sothat on the return of the parts to normal position the carriage truckand platen carrier, under the influence of the spring drum 66, will bepermitted to move the distance of one letter space. The operation isrepeated until the line of writing is finished, the carriage truck andplaten carrier moving step-bystep across the top plate of the machineafter which the plathn is returned across the top plate until it ispositioned to begin a new line. The line space member-A3 is then lifteduntil free fromthe detent 46, whereupon the platen is drawn forward by.

means of the handle 4d and against the pull of the draw spring 38untilthe second'perforatioh 45 is in position to engage with the detent-46. The member 43 is then lr'iwered until the detcnt engages with thesecond perforation. The second and succeeding lines may then be writtenin the manner described. When the writing has been completed the stencilsheet may be re moved by lifting" the platen carrier to thepositionindicated in Fig. 3 and pressing down and turning the grippingfinger or member 25.

. It willbe noted that I have, provided means for suitably feedingandcentrolling a Work sheet or stencil.

without doing injury to the said work sheet; that the said meanscomprises a platen or stencil support having a Hat surface havingpreferably a soft facing of felt or the like and provided with suitableguiding and holding means for the work sheet, said means comprising 2-stencil oocketformed in art by the retainin piece 23 i l i v and theretaining pieces 2, said pocket engaging the rectangular stencilsheet onthree sides and theclanip- 1135 ing nc-ans clamping said sheet at tsfourth side; that a series of puncturing elements or type bars havi afixed support are adapted to cooperate with the platen; that means areprovided to feed the platen in one direction or; from side to side,transversely of the machine for" letter spacing and in a direction atright angles there further that I have provided mechanism of simple andi to longitudinally'oi the, machine forlinespacing; and

inexpensive construction and'which will well and practically accomplishthe desired results. It is further to be noted that though the inventionis particularly adapted iorsteneii Writing'it is not limited to thatspecific kind of work but may equally Well be employed "for other kindsof writing.

I do not desire to be limited to the'particnlar eonstruction andarrangement herein shown and described. 7 3
